Hi all, I am in need of an epoxy expert here. I built a 16 Shearwater in my garage using MAS. No problem heating, it went well. My dilemna is for my boat...the stantions for the bow rail (core) are wet/soft. I need to remove the bowrail, drill screw holes bigger, backplate underneath, fill with thickened epoxy and redrill, mount, install for the rail to be strong again. The problem is I must do this outside and heating the cabin, even under the tarp will be very difficult. I like using MAS. What recipe can I use for cooler weather? What is the coolest the epoxy will cure at? Would I use a faster cure or slower cure? Thanks for any help here. - Joe.
I'd suggest contacting MAS customer support - I e-mailed them with similar questions about a year ago and they were very helpful with the producet/temperature requirements. I believe they said that the cure with the slow hardener would be OK down to 30 degrees, but it would take a long time to cure. Definitely good to check with them directly though.
Thanks Kathy. I went to their tech help site and they have a chart with different cures and temperatures. Down to 41 degrees the slow cure is not recommended and the fast will fully cure in about 8 days, which is ok by me as long as it cures. Will take longer dipping into the 30’s at night but time is not important. Seems 2 weeks should be enought for a full cure. Thanks for the help.
